Honda Innova 125i '09 - strange sound

[lobora]

Hi all,
I'm looking for Innova 125i owners
I would like to buy one and need help.

I found one good looking Innova but after the starting of engine it gives a strange sound from somewhere under the seat. It's like not so loud squeak or whistling. Can it be a fuel pump? Is it normal behaviour or not?
The bike is looking great, engine starts and works fine.. it's almost new - 5000km!


The new pump costs about $400!!!

Please help.

Regards,
Lobora
